PAINT REMOVING TOOL Harold Christopherson, Bronx, N. Y. Application July 1.5, 1942, Serial No. 451,085Y

e claims. (ci. 30-277) i My invention relates to the removal of paint,

" particularly on the hulls of "ships, and has among `its objects and advantages the provision of an improved paint removing tool. In the accompanying drawing:

Figure 1 is an end View of a tool inaccordance I," with my invention;

Figure 2 is a sectional viewalong thelline 2-2 of Figure 1;

Figure 3 is a sectional View taken along the line 3-3 of Figure 2; and

Figure 4 is a sectional `view of a modied form of the invention. I

In the embodiment selected for illustration, I n

make use of a head IIlhaving a shank VI2 for connection with a vibrating tool (not shown).

To the head IIJ is connected a casing I4by screws I6, which casing is provided with an` end wall I8 shanks 22 of paint removing tools 24 having paint cutting blades 26.

Figures 1, `2 and 3 illustrate ve tools `24, and

` each shank 22 is loosely positioned in a recess 28 ,having openings for loosely receiving` the v in the head I0. The shanks 22`are arranged in parallelrelationship and are free to rotate about their longitudinal axes while in'operation.

In removing paint, the head I0` is connected with a suitable vibrating tool and the blades 26 are brought `into edge engagement `with the desirable to `latch the tools 24 against accidental dropping from` the head and the housing. Such means comprises a cable 30 having one end provided with a loop 32 encircling the shank 22 of y the central tool 24.

over the remaining Shanks, 22 and connected at 'I'he cable is then wound 34 with oneA end of a lever 36 pivotally connected at 38 with the end wall I8. The lever 36 is bent so that the tension ofthe cable 30 holds the lever rmly against one of the Shanks 22 when the lever is pivoted to the position of Figure 1 for rmly clamping the tools in position. A slight pivotal movement of the lever in a counterclockwise direction loosens the cable 3U to free the tools. v

Figure 4 illustrates a slightly different form l of invention wherein the tool shanks 22 are loosely supported in tubes 4U Xedly connecting an end plate 42 with the head 44 corresponding to the head III. In other respects the tool structureof Figure 4 is identical with that illustrated in Figures 1 through 3.

The tool embodies a plurality of paint cutting blades which perform 'an eilicient paint cutting function when vibrated, with the paint cutting tools loosely `mounted so as to rotate freely under the inuence ofthe vibratory motion. Thus the tool is designed to span a relatively large area to facilitate removalof the paint in an expeditious manner. Y

Without further elaboration, the foregoing will so fully illustrate my invention, that others'may, by applying current knowledge, readily adapt the same for use under various conditions of service.

Iclaim:

1. A` paint cutting tool comprising a vbratory head, tubes xedly connectedwith said head, a

platexedly connected with said tubes, paint cutting tools having shanks loosely supported in said tubes, and flexible means coactng with said tools and said plate to frictionally secure the tools against accidental displacement. I 5,

2. Apaint removing tool comprisinga head adapted for connection with a vibrator, said head being provided with ahousing having an end wall provided with openings, said head having recesses coaxially positioned with said openings,I I paint cutting tools having blades and shanks loosely supported in said openings vand said recesses for unrestrained rotation about the axes of the Shanks, a cable attached at one end to one `of said Shanks and wound about the other Shanks,

and a lever pivotally connected with said end wall and connected with the other end of the cable for placing the cable under tension to frictionally hold the tools against accidental displacement.`

HAROLD CHRISTOPHERSON.
